Definitions

  • the present invention relates to a baling press according to the introductory portion of claim 1 and to a method of operating a baling press according to the introductory portion of claim 7.
  • Such a baling press and such a method are disclosed in European patent application 2 941 951 .
  • a baling press typically includes a bale pressing channel in which a pressing ram is reciprocally movable to and fro, new material to be baled being added each time after the press has been retracted.
  • the counter pressure against which the bales are pressed is obtained by resistance encountered by the material as it is pressed through the pressing channel, which, to that end, has a cross-section that decreases in downstream direction over at least a portion of its length.
  • Initial counter pressure may be obtained by mounting obstacles in the pressing channel.
  • string material is usually tied around the bales.
  • the string material is for instance wire or rope material.
  • the wire material is for instance steel or plastic wire and the rope material is for instance plastic or natural fiber material that may be twisted or braided and include one or more strands of twisted fiber material.
  • a number of loops of the string extending around the bale is usually obtained by feeding strings from two sources along opposite sides of the bale to be formed, tying the strings together near the downstream end of the bale to be formed and tying together the strings near the upstream end of the bale after the material for forming that bale has been pressed.
  • Tying together the strings is usually accomplished by twisting or twining end sections of the wire material from a mutually parallel configuration as is for instance described in U.S. patent 3 667 377 or by tying ends of rope material to each other as is for instance described in European patent application 2 941 951 .
  • loop supply members for passing the string from one side of the bale pressing channel to an opposite tying side where it is to be tied to the string fed from that tying side.
  • loop supply members in the form of rods having a loop supply member at a distal end are provided.
  • An example of such a loop supply member is described in more detail in U.S. patent 5 255 597 .
  • the loop supply members are extended via slots in the pressing ram and passages in walls of the pressing channel, catch the strings at the side opposite the tying side and are retracted to pull the strings over to form a temporary loop projecting until out of the pressing channel.
  • the loop supply members also entrain the string into temporary loops so that the temporary loops of strings from both sides commonly extend along the loop supply members so that the strings can be tied to each other.
  • this object is achieved by providing a baling press according to claim 1 and a method of operating a baling press according to claim 7.
  • the slot clearing member When the slot clearing member is moved from its retracted position to its extended position projecting through the slot and across the bale pressing channel, the slot is effectively cleared from material (potentially) clogging up the slot, even if much material has entered the slot and/or the material sticks to an inner surface of the slot, and discharged out of the slot on a side of the pressing channel opposite of the location where the slot clearing member is when it is in its retracted position.
  • the baling press shown in Figs. 1 and 4 has a pressing channel 1 in which a ram 2 is displaceable by a hydraulic cylinder 3 mounted between the ram 2 and a suspension bracket 4.
  • a ram 2 is in its most advanced position while in Fig. 4 the ram 2 is in its most retracted position.
  • a feeding chute 5 communicates with a pressing chamber area 6 of the pressing channel 1 via a passage 7 forming a downstream end of the feeding chute 5.
  • the pressing chamber 6 is defined by the stroke volume of a face of the ram 2 facing in pressing direction.
  • a prepress valve 8 is pivotable about a pivotal axis 9 and has a flat wall 10 which, in the closed position shown, closes off the passage from the feeding chute 5 to the pressing channel 1 and, in opened position, is disposed in a wall of the feeding chute 5.
  • the prepress valve 8 furthermore has a surface 11 substantially curved around the pivotal axis 9, which surface in closed position bounds the feeding chute 5 in axial direction.
  • Material 17 to be pressed may already be deposited into the feeding chute 5, while the prepress valve 8 is closed.
  • the prepress valve 8 is opened, all or a portion of the material to be pressed drops into the pressing chamber 6 and may form a pile aside the prepress valve 8.
  • the prepress valve 8 is closed again, if a pile has formed aside the prepress valve 8, a volume of the material is precompressed in the pressing chamber 6 by the closing of the prepress valve 8.
  • the pressing ram 2 is moved to its most forward position ( Fig. 1 ) compressing the precompressed material while simultaneously new material to be pressed can be deposited into the feeding chute 5.
  • each bale may be obtained by a single or a plurality of compression cycles of the pressing ram 2 each time compressing material newly fed into the pressing chamber 6.
  • Counter pressure in the pressing channel 1 against which a bale is pressed in the pressing chamber 6 and pushed out of the pressing chamber 6 is obtained by resistance encountered by the material of previously compressed material formed into bales 18, 19, 20 as it is pressed through the pressing channel 1 while compressed between top and bottom walls 12, 13 and side walls of the pressing channel 1.
  • the pressing channel 1 may for instance have a cross-section that decreases in downstream direction over at least a portion of its length and/or one or more walls of at least a downstream portion of the pressing channel may resiliently be pressed inwardly.
  • Initial counter pressure may be obtained by mounting obstacles in the pressing channel 1 that are pressed out by the first bale.
  • the string material may for instance be wire or rope material.
  • the wire material is for instance steel or plastic wire and the rope material is for instance plastic or natural fiber material that may be twisted or braided and include one or more strands of twisted fiber material.
  • the string material is wire material that is tied by twisting.
  • other string material and other manners of connecting such as knotting, welding or use of fasteners, can also be applied.
  • each first wire 24 fed from below has been tied, by means of a twist 46, to an upper wire 26 fed from above during the tying of a previous bale (see also Fig. 3 ).
  • a tying assembly is provided for arranging a loop 21-23 of wire material 24, 25 around a bale and for holding a pair of end portions 28, 29 (see Fig. 2 ) of the loop 23 next to each other.
  • the tying assembly includes lower guide rollers 30, 31 located closely along the bottom of the pressing channel 1, for guiding lower wires 24 fed from respective spools (not shown) into the pressing channel 1 and loop supply members 32, 33 for pulling up lower wires 24 from adjacent to the bottom of the bale pressing channel 1.
  • the loop supply members 32, 33 are in the form of rods reciprocally movable in longitudinal direction of the rods and are suspended in positions on a first, upper side of the bale pressing channel 1 and in pressing direction of the feed passage 7 and each have a hook adjacent to a free end for catching the lower wires 24 on a second, lower side of the bale pressing channel 1 and for catching the upper wire on the upper side of the bale pressing channel 1.
  • An example of such a loop supply member is described in more detail in U.S. patent 5 255 597 .
  • the loop supply members 32, 33 are movable between an extended, lowermost position as indicated by dash and dot lines in Figs. 1 and 4 and a retracted, uppermost position as shown in full lines in Figs.
  • the loop supply members 32, 33 are on the upper side of the bale pressing channel.
  • the loop supply members 32, 33 are extended through passages 27 in an upper wall 12 of the pressing channel 1 and through slots 34 in the pressing ram 3, catch the lower wires 24 that extend closely along the bottom of the pressing channel 1 and pull up loops of the wires 24 to form temporary loops projecting above the pressing channel 1.
  • the loop supply members 32, 33 also catch and entrain the upper wires 25 into temporary loops so that the temporary loops of upper and lower wire material 24, 25 commonly extend along the loop supply members 32, 33 as is shown in Fig. 2 .
  • first side is the upper side of the bale pressing channel and the second side is the lower side of the bale pressing channel
  • first and second sides may also be opposite lateral sides of the bale pressing channel or upper and lower sides may be reversed.
  • the tying assembly furthermore includes upper guide rollers 35, 36, 37, 38 at the top side end of the pressing channel 1, for guiding upper wires 25 fed from respective spools into the pressing channel 1 and to the area where the temporary loops are formed.
  • the slot clearing member 15 in its retracted position is at a top side of the bale pressing channel 1, so that it does not increase the footprint of the bling press.
  • the prepress valve 8 is pivotably mounted and pivots out of the feeding chute 5 in a sense of rotation 56 generally opposite to the pressing sense of rotation.
  • the slot clearing assembly 15 is mounted closely adjacent to the prepress valve 8 in a direction 56 generally opposite to the pressing direction, it is not in the way of pivoting movement of the prepress valve 8, because the prepress valve 8 is hollow and open on its side facing the slot clearing assembly 15 when the prepress valve 8 is closed and a hollow internal space of the prepress valve 8 has a radius extending radially outside of the slot clearing assembly 15, so that at least a portion of the prepress valve is in a hollow space inside the prepress valve when the prepress valve is open.
  • This principle may also be applied to a prepress valve that opens and closes along a different path of movement, such as in a horizontal direction.
  • Passages 27, 77 are provided in the top wall 12 and, respectively, bottom wall 13 of the pressing channel.
  • the loop supply members 32, 33 can be extended and retracted through the passages 27, 77.
  • the closure 53 for closing off one of the passages 27 is movable between an open position for allowing at least one loop supply member 32, 33 to extend through said passage 27 and a closed position filling up the passage such that an inner surface 58 of the closure 53 is flush with an adjacent inner surface portion 59 of the bale pressing channel 1.
  • the passage 27 has passage side walls 59 that are oriented in longitudinal directions 60 of the bale pressing channel 1, while at least sections of the side walls 59 converging outwardly of the bale pressing channel 1 and the closure 58 has closure sidewalls 61 also oriented in longitudinal directions 60 of the bale pressing channel 1. At least sections of the closure side walls 61 converge outwardly of the bale pressing channel 1.
  • the converging side wall sections 59, 61 of the passages 27 and of the closure 58 mutually engage for retaining the closure 58 against outward movement when in closed position against outwardly oriented compression forces exerted by the material being baled.
  • closure 73 and actuator 72 for closing-off and leaving open the passage 77 in the bottom wall 13 are of a similar design as the closure 53 and actuator 52 for closing-off and leaving open the passage 27 in the top wall 12 of the pressing channel 1.
  • FIGs. 9 and 10A-10C an alternative passage 127 for allowing the loop supply members 32, 33 to be extended through a wall 112 of the bale pressing channel 101 is shown.
  • the closure 158 is movable from a closed position 158 ( Figs. 9, 10A, 10B ), in which a wire 24 runs through a slot 166 in an inner surface of the closure 158, to an open position 158' in an opening direction 160 transverse to a longitudinal pressing direction 162 of the bale pressing channel 101.
  • a closed position 158 Figs. 9, 10A, 10B
  • an open position 158' in an opening direction 160 transverse to a longitudinal pressing direction 162 of the bale pressing channel 101.
  • a locking member 163 is guided by a guide track 165 for movement only in directions 164 generally transverse to the opening direction 160 and movable between a locking position 163 ( Fig. 10A ) locking the closure 158 in the closed position 158 and a releasing position 163' ( Figs. 9, 10B and 10C ) allowing opening of the closure from the closed position 158 and closing the closure from the opened position 158' into the closed position 158.
  • the locking member 163 in the locked position reliably prevents the closing member 158 from being pressed open by compression forces exerted by material in the pressing channel 101. This allows actuators 152, 164 for opening and closing the closure 158 and for moving the locking member between the locking and releasing positions to be dimensioned lightly. If a plurality of passages 127 in a row is to be closed off simultaneously. Each actuator is preferably coupled to a plurality of closures or locking members for simultaneous operation of the closures and locking members for closing off that row of passages.
  • a further example of a baling press according to the invention is shown.
  • this press bales 18-20 around which loops 21-23 of string material including connections 40, 46 are tied as in the baling press according to the previous example, except that the loops 21-23 extend in a horizontal plane.
  • the string material 124, 125 is supplied generally horizontally from opposite lateral sides of the pressing channel 101.
  • the tying assembly with loop supply members 132, 133 (when retracted) and twisters 139, 143 as well as the slot clearing assembly 115 are both arranged on the same lateral side of the pressing channel 101 and accordingly, the slots in the pressing face of the ram 102, through which the loop supply members 132, 133 are passed are then oriented horizontally.
  • Passages in the walls of the pressing channel 101 for allowing the loop supply members 132, 133 to pass through can be closed with closures 158 as shown in Figs. 9 and 10A-10C .
  • the tying assembly and the slot clearing assembly 115 are arranged on opposite sides of the feeding chute 105.
  • the slot clearing assembly is arranged to a lateral side of the pressing channel
  • the slot clearing members may also be arranged to pass through a section of the pressing channel under the feeding chute. This allows the retraction immediately prior to clearing of the slots and the stroke immediately after clearing of the slots to be relatively short.
